NaCl Salt(g / 100g)
Meter reading (D) x Dilution Factor (C/B) x 100
1.1g NaCl x 100ml (g) x 100g 100ml (g) 10.0618g
Na(mg / 100g)

According to the National Health Group Pharmacy in Singapore, adults should limit the amount of salt to one teaspoon per day, which is about 5g of salt or 2g of sodium. To ensure that you are not taking more than that amount, always check the amount of sodium per serving on the nutrition information panel of your chili sauce and other packaged or processed food. If that information is not available, simply perform a quick salt test with LAQUAtwin Salt-22 pocket meter.
